This article presents the development of a concept for the distribution and migration of data to several databases within a distributed knowledge base Thus a concept for a load dependent and application speci c migration of data is introduced which takes into con sideration the number and sort of accesses to the data The main part of the migration method is a distri bution function which genera...

We have analyzed the distribution of glucosamine-labeled polymers on the cell surface, in the growth medium, and inside the cell and the net turnover of these polymers during the process of malignant transformation of chick embryo fibroblasts by Rous sarcoma virus. The distribu tion of label and the turnover kinetics for hyaluronic acid, total glycoproteins, and chondroitins were found to be id...

Evaporation of a liquid into a vacuum occupying a half space is investigated on the basis ofthe BGK equation for a three-dimensional gas linearized about a drifting Maxwellian distribu-tion. The theory of singular integral equations is used and numerical results are given. ZusammenfassungDie Verdampfung einer Fliissigkeit im Vakuum, die den Halbraum fiillt, wird untersuchtmi...

A repository is a shared database of information about engineered artifacts. We define a repository manager to be a database application that suPports checkout/checkin, version and configuration management, notification, context management, and workflow control. Since the main value of a repository is in the tools that use it, we discuss technical issues of integrating tools with repositories. ...

Our laboratory is engaged in an ongoing analysis of a 103-compound data set containing reliable intravenous pharmacokinetic parameters in the rat, dog, monkey, and human, and we have previously reported our findings regarding extrapolation of clearance. In this article, we report on our findings regarding volume of distribution and mean residence time. Various allometric and nonallometric metho...

Aims: T1 /(podoplanin) is abundantly expressed in the alveolar epithelial type I cells (ATI) of rodent and human lungs. Caveolin-1 is a classical primary structural protein of plasmalemal invaginations, so-called caveolae, which represent specialized lipid rafts, and which are particularly abundant in ATI cells. The biological functions of T1 in the alveolar epithelium are unknown. Here we repo...

Artificial neural networks (ANNs) have become one of the most promising tools for rainfall simulation since a few years ago. However, most of the researchers have focused on rainfall intensity records as well as on watersheds, which generally are utilized as input records of other hydro-meteorological variables. The present study was conducted in Kechik station, Golestan Province (northern Iran...

The Tumbesian region of Peru and Ecuador, located within a global biodiversity hotspot, is home to large number endemic little-known species. Endemic terrestrial birds (tinamous, cracids, doves) are at increased risk extinction due restricted distribu-tion exposure habitat conversion. In this study, we used 24 camera traps in Cerros de Amotape National Park (northwestern Peru) record three site...
